gins, and the invention has for its object to 7 provide mechanism'of the character: specified, for more thoroughly removing the lint from the seed, wherein a drum is provided havingon its periphery a coating of emery, together with a cutter or separating head of metal, and curved to fit the periphery of the drum, to bring the seed into close prox imity to the coating, in order that the coating may grasp the lint, and whereln means is provided for permitting the cutter or separating head to be adjusted with respect to the drum, and wherein. other mechanism is provided for cleaning the lint from the drum,

In the drawings: Figure 1 is a top plan view of the improved gin; Fig. 2 isa side view Fig. 3 is an enlarged section through the drum and cutter or separating head; Fig.4 is a detail sectional view. at right angles to Fig. 3, and Fig. 5 is a sectional detail view of a portion of the head.

In the present embodiment of the invention a suitable supporting frame 1 is provided, upon which is j ournaled a shaft 2, the shaft beingjournaled in bearings. 3 on the frame, and having a pulley 4 for engagement by a belt from a suitable source of power to rotate the shaft. The shaft is provided with a second pulley 5 at the opposite end from the pulley 1, and a belt 6 connects the pulley 5 with pulleys 7 and 8 on shafts 9 and 10, respectively, also journaled in the frame, the shaft 10 being a stub shaft and the pulley 8 being an idler pulley.

The shaft 9 is journaled in bearings 11 on the frame, parallel with the shaft 2, and the shaft 2 supports a drum for cleaning the any suitable. or desired manner, each hub having a radial flange 13, and the heads 14 of the drum are provided with central openings for receiving the hubs 12, the

. flanges 13 abutting the outer faces of the heads, and being secured thereto by screws Specification of Letters Patent.

15 or the like. The heads are connected by staves 16, which form the periphery or body of the drum, and this drum is provided With a coating of emery, indicated at 17, which is held to the surface of the drum by glue or the like. The coating of emery grasps the lint on the seeds, and removes it from the seeds, and a cleaning drum is secured to the-shaft 9, for cooperating with the drum 16 to remove the lint therefrom. TlllS cleaning drum consists of a series of .heads 18 which are connected by bars 19 extending parallel with the'shaft 9, and each bar 19 carries a'se'ries of bristles 20. The shafts2 and 9 are so'arranged with respect to each other-that the free ends of the bristles 20 will contact with the peripheral sur- 1 face of the drum to remove the lint therefrom.

The belt 6 before mentioned passes over the pulley 5, and over the idler 8, and the 7 lower run of the belt engages above the pulley 7. Thus the. drum 1920 is rotated N in the opposite direction to the drum 16,

and the wheel or pulley 8 is a tension pulley.

The shaft 10 is mounted in bearing standards 21, which have'guided vertical movement outhe frame, and means is provided for hold ng the standards in adjusted position. By moving the standards vertically,

. the tension of the belt 6 may be varied.

A cutter or separating'head is provided in connection'with the peripheral surf-ace of the drum, 16. This head is cast from suitable metal, and the head is arched trans versely to correspond approximately with the curvature of the drum, and isalso arched longitudinally of the drum, as shown in Fig.

A 4:. The head is a plate 22 of substantially triangular form, having its apex at the front of the machine, and its base at the rear or adjacent to the brush, and the plate is also provided with a central rib 23 on its upper At each end of the rear or base the plate is provided with an outwardly extending lug 25, and

. each-0f these lugs has connected thereto an lint from the seed. This drum consistsrof hubs 12 which are secured to the shaft in adjusting rod 26. The peak or apex 24 of the plate is at the center of the drum. Each of these rods 26 passes through the lug at approximately the center of the rod, and the rod is threaded at its ends and intermediate its ends, and lock nuts 27 are threaded onto each rod on opposite sides of the lugs 25. Each rod passes at its upper end through a bar of the supporting frame, and nuts 28 are threaded onto the rod above and below the bar, to hold the rod in adjusted position. The lower end of the rod also passes through a bar of the supporting frame, as shown in Fig. 2, and a nut 29 is threaded onto the rod on the under side of the bar.

An adjusting rod 30 is connected with the front end or apex of the head, the said rod engaging a threaded boss 31 at the center of the head, andat its upper end the rod 30 passes through an opening in a bar 32 supported transversely of the frame, and nuts 33 are threaded onto the rod above and below the bar. It will be noted that the bar is notched or recessed at opposite corners, at the point where the rod 30 passes through the same, so that the nuts 33 will have fiat bearing surfaces perpendicular to the axis of the rod.

It will be evident that by means of the I nuts 33 the peak or apex of the head may be adjusted toward and from the drum. The side edges of the head incline outwardly at anacute angle from the central longitudinal line of the frame, to the ends of the drum, as shown in Fig. 1, and the distance from the apex of the plate to the base line corresponds approximately to the diameter of the drum. The plate is further reinforced by ribs 34, which diverge in opposite directions at an acute angle from the rib 23 intermediate its ends. The side edges of the head are enlarged slightly, as shown in Figs. 4 and 5, and these edges are inclined or beveled on their under faces parallel with the surface of the drum, as indicated at 36. These surfaces 36 fit closely against the periphery of the drum, when the head is adjusted closeto the drum, while at the rear of the head they are spaced apart from the drum, as shown in Fig, 3.

In operation, the head is adjusted as shown in Fig.3 so that the peak or apex 24 of the head is near the peripheral surface of the drum. The cotton to be ginned is fed at the apex of the head, and as the drum rotates 1n the direction of the arrow in Fig. 3,

cannot pass between the plate 22 and the drum, it will be gradually moved laterally with respect to the plate, and longitudinally of the drum in opposite directions, and will berolled over and over on the surface of the drum, and since the lint will stick to the powdered emery coating, the seeds will be stripped and cleaned, when they are'finally delivered at the ends of the drum and near the base of the head. The lint which adheres to the surface of the drum is removed by the brush, and the said brush is geared drum. The bristles will remove the lint and W111 deposit it in rear of the brush,

while the seed will fall into a suitable receptacle arranged below the frame. The coating of emery does not cut the fiber, nor does the drum injure the seed. The fibers of the lint come off of the seed at their full length, and the head may be adjusted with respect to the drum in accordance with conditions that may arise.
